It is faster than the specifications seem to indicate. As noted, the default clock speed for the Pi is 900 MHz. But with its 900 MHz clock speed that can be safely overclocked to 1 GHz and its 1 GB RAM, this small computer can run really bigger and powerful applications.
Very wisely, the Foundation chose a CPU with floating-point support, often referred to as hard float, which offers greater performance than so-called soft float-only chips. Operating systems available for the Pi take advantage of that extra power and speed.
Finally, the Pi has a fairly beefy Graphics Processing Unit (GPU) with a fast 3D core that is capable of BluRay quality playback, using H.264 at 40MBits/s (https://www.raspberrypi.org/help/faqs/#generalSoCUsed).
